Title: Circuits and methods related to switchless carrier aggregation in radio-frequency receivers
Inventor: IBRAHIM ENGIN PEHLIVANOGLU
IPC: H04B1/00
Filed: 2015-04-08
Abstract: A multiple input low noise amplifier circuit may include a first input stage 142 for receiving a first RF signal in a first band, and a second input stage 144 for receiving a second RF signal in a second band. The signal paths may include filters, not shown, for the respective bands. Each of the input stages 142 and 144 may act as a current converter that provides amplification for its respective RF signal. The processed first and second RF signals may be added at common node 136 and further processed by a transistor 146 to provide an output RF signal at output node 138. The first current converter 142 and the transistor 146 operate together as first cascode amplifier. Similarly, the second current converter 144 and the transistor 146 operate together as second cascode amplifier. Alternatively (fig.9) each input stage may be coupled to its own cascode transistor. Bias switches S1 and S3 may be used to turn on one or other amplifier, or both amplifiers, to combine signals. The signal paths themselves are free of switches, allowing the carrier aggregation circuit to operate with reduced noise figure.
